The class represents IEEE Std 421.5-2005 type ST7B model.
The class represents IEEE Std 421.5-2005 type ST7B model. This model is representative of static potential-source excitation systems. In this system, the AVR consists of a PI voltage regulator. A phase lead-lag filter in series allows introduction of a derivative function, typically used with brushless excitation systems. In that case, the regulator is of the PID type. In addition, the terminal voltage channel includes a phase lead-lag filter. The AVR includes the appropriate inputs on its reference for overexcitation limiter (OEL1), underexcitation limiter (UEL), stator current limiter (SCL), and current compensator (DROOP). All these limitations, when they work at voltage reference level, keep the PSS (VS signal from Type PSS1A, PSS2A, or PSS2B) in operation. However, the UEL limitation can also be transferred to the high value (HV) gate acting on the output signal. In addition, the output signal passes through a low value (LV) gate for a ceiling overexcitation limiter (OEL2).

Load whose behaviour is described by reference to a standard model <font color="#0f0f0f">or by definition of a user-defined model.</font>
A standard feature of dynamic load behaviour modelling is the ability to associate the same behaviour to multiple energy consumers by means of a single aggregate load definition. Aggregate loads are used to represent all or part of the real and reactive load from one or more loads in the static (power flow) data. This load is usually the aggregation of many individual load devices and the load model is approximate representation of the aggregate response of the load devices to system disturbances. The load model is always applied to individual bus loads (energy consumers) but a single set of load model parameters can used for all loads in the grouping.

Reference to the superclass object.
Measurement value may be incorrect due to a reference being out of calibration.
Value has been replaced by State Estimator. estimatorReplaced is not an IEC61850 quality bit but has been put in this class for convenience.
This identifier indicates that a supervision function has detected an internal or external failure, e.g. communication failure.
Measurement value is old and possibly invalid, as it has not been successfully updated during a specified time interval.
Measurement value is blocked and hence unavailable for transmission.
To prevent some overload of the communication it is sensible to detect and suppress oscillating (fast changing) binary inputs. If a signal changes in a defined time (tosc) twice in the same direction (from 0 to 1 or from 1 to 0) then oscillation is detected and the detail quality identifier "oscillatory" is set. If it is detected a configured numbers of transient changes could be passed by. In this time the validity status "questionable" is set. If after this defined numbers of changes the signal is still in the oscillating state the value shall be set either to the opposite state of the previous stable value or to a defined default value. In this case the validity status "questionable" is reset and "invalid" is set as long as the signal is oscillating. If it is configured such that no transient changes should be passed by then the validity status "invalid" is set immediately in addition to the detail quality identifier "oscillatory" (used for status information only).
Measurement value is beyond a predefined range of value.
Measurement value is beyond the capability of being represented properly. For example, a counter value overflows from maximum count back to a value of zero.
Source gives information related to the origin of a value. The value may be acquired from the process, defaulted or substituted.
A correlation function has detected that the value is not consitent with other values. Typically set by a network State Estimator.

The RUC Award of a resource is the portion of the RUC Capacity that is not under RA or RMR contracts. The RUC Award of a resource is the portion of the RUC Capacity that is eligible for RUC Availability payment.
The RUC Capacity of a resource is the difference between (i) the RUC Schedule and (ii) the higher of the DA Schedule and the Minimum Load.
The RUC Schedule of a resource is its output level that balances the load forecast used in RUC. The RUC Schedule in RUC is similar to the DA Schedule in DAM.

Accumulation behaviour of a reading over time, usually 'measuringPeriod', to be used with individual endpoints (as opposed to 'macroPeriod' and 'aggregate' that are used to describe aggregations of data from individual endpoints).
Salient attribute of the reading data aggregated from individual endpoints. This is mainly used to define a mathematical operation carried out over 'macroPeriod', but may also be used to describe an attribute of the data when the 'macroPeriod' is not defined.
Argument used to introduce numbers into the unit of measure description where they are needed (e.g., 4 where the measure needs an argument such as CEMI(n=4)). Most arguments used in practice however will be integers (i.e., 'denominator'=1).

Flow direction for a reading where the direction of flow of the commodity is important (for electricity measurements this includes current, energy, power, and demand).
Indication of a "harmonic" or "interharmonic" basis for the measurement. Value 0 in 'numerator' and 'denominator' means not applicable.
Time period of interest that reflects how the reading is viewed or captured over a long period of time.
Identifies "what" is being measured, as refinement of 'commodity'. When combined with 'unit', it provides detail to the unit of measure. For example, 'energy' with a unit of measure of 'kWh' indicates to the user that active energy is being measured, while with 'kVAh' or 'kVArh', it indicates apparent energy and reactive energy, respectively. 'power' can be combined in a similar way with various power units of measure: Distortion power ('distortionVoltAmperes') with 'kVA' is different from 'power' with 'kVA'.
Time attribute inherent or fundamental to the reading value (as opposed to 'macroPeriod' that supplies an "adjective" to describe aspects of a time period with regard to the measurement). It refers to the way the value was originally measured and not to the frequency at which it is reported or presented. For example, an hourly interval of consumption data would have value 'hourly' as an attribute. However in the case of an hourly sampled voltage value, the meterReadings schema would carry the 'hourly' interval size information.
